Since March, Demi Lovato has been releasing rock versions of some of her older pop hits, including “Heart Attack” and “Sorry Not Sorry." She's been busy promoting her album Revamped, a collection of these re-recorded singles, which will be released on September 15. When she made the latest stop on her press tour at Serius XM studios on September 11, we noticed her bob had magically "grown" into chest-length waves overnight.

Lovato appeared in a monochromatic black outfit, paired with matching jet-black loose waves, parted down the middle with the ends flowing towards her chest. Her curled hair looked glossier than her peach lip gloss.

Peach eye shadows that matched the hue of her gloss were blended onto her lids as well. Thin, sharp cat eyes were drawn on, too, but they were mostly covered by her extra long, wispy lashes that nearly touched her eyebrows.

Five days prior to her Sirius XM appearance, she posted photos of her noticeably shorter hair that barely grazed her shoulders on Instagram. In fact, she's been loyal to her blunt, chin-grazing bob since as early as April. She played around with a few other haircuts, including a choppy shaggy cut and bangs, prior to April, but her bob has been a consistent style.

This longer hair is more than likely the result of some very well-installed extensions, but honestly, we don't care how she got this lenghty hair — we're just please to see Lovato experimenting more in general.
